IMPROVEMENT IN MACHINES FOR WINDING SILK FLOSS.

Specification forming part of Letters Patent No. l 50,581, dated May 5,1874; application filed April 1, 1874.

To all whom it may concern:

Be it known that I, GEORGE E. JENK1Ns,of the city of Philadelphia, inthe State of Pennsylvania, have invented an Improved Machine for WindingSilk Floss, of which the following is a specification:

The object of my invention is to produce an automatically-windingmachine that will wind the iioss around the conical bobbin in regularand uniform spirals in short longitudinal sections, overlapping eachother as they are form ed around the bobbin from its head to its smallerend, and in arapid manner; and this I accomplish by means of alongitudinally-reciprocating advancing carrier of the running flossoperated by a combination of mechanical de vices, which will hereinafterbe described in full, clear, and exact terms with reference to theaccompanying drawings, in which- Figure 1 is a front elevation of mysaid improved machine; Fig. 2, au elevation of the rear side of the same5 and Fig. 3 an elevation of one end of the same.

The reciprocating advancing carrier A of the iioss (not shown) issupported upon the top of a frame, B C, so as to slide longitudinallybackward and forward in stationary guide bearings c c', an eye, 2, forthe ruuning tloss being fixed to the upper edge of the sliding carrier Aat a point, which, during the full extent of the reciprocating motionsof the said carrier, will cause it to be carried from opposite the headof the conical bobbin D to a point opposite, or nearly opposite, to itssmaller end. Motion is given to the carrier A directly by an uprightlever, E, which bears against .it in one direction, and a spiral spring,AF, which draws it back in an opposite direction. The lever E is of thethird order, has its fulcrum-pin c fixed near the bottom of the frame BC, with its upper or weight end c bearing against a knob, a', fixed inthe rear side of the sliding carrier A. (See Fig. 2.) The power point ofsaid vlever E consists of a grooved pulley, 4i, which is attached to anadjustable arm, 6. Motion is given to lever E,

and consequently to the sliding carrier A, by the vertically-slidingmotions of an upright bar, Gr, that carries an inclined bar, H, whichhas its lower end pivoted to bar G, and its upper end pivoted to one endof a rack,

I, the teeth of which gear with the teeth of a pinion, K', which isrigidly fixed concentrically to the side of an obliquely-toothed wheel,K, that is driven by a worm-wheel, L, beneath, the shaft of which has aratchettoothed wheel, M, fixed thereon, which teeth come in contact witha spring-pawl, N, as the vertically-sliding bar G rises, and thusrotates the worm-wheel L, and consequently the wheel K and pinion k',and these move the rack I inward and increase the inclination of the barH, which bears in the groove of the pulley 4. The requiredverticalmotions of the sliding bar G, with its said appendages H I K k LM, are given by a spur-wheel, O,

which has a wrist-pin, o', that is connected to the said bar by acoupling-rod, P, the rotary motions of the wheel O being by a pinion, Q,

`on the shaft R, which has a grooved pulley, S,

on its opposite end, driven by a cord that connects it with the maindrivin g-wheel T of the machine. l Near the midlength of the shaft R agrooved pulley, 1", is fixed, which, by a cord, or band gives rapidrotary motion to a small shaft and pulley, V, which carries theremovable or changeable bobbins, upon which the flossis to besuccessively wound. The skein or hank from which the floss is wound runsaround two adjustable bobbins, W W, which are supported upon the top ofthe frame-B C and directly opposite to the bobbin D. For the purpose oflimiting the inward movement of the sliding carrier A, so as to preventthe eye or loop 2 thereof from carrying the running oss beyond the outerend of the bobbirn D, a dat plate, Z, (see Fig. 1,) is Xed to projectfrom one side of the rack I, and a cam having two opposite projections,Y Y, fixed to the pinion la', so that when the said pinion has carriedthe rack I far enough inward, one ot' the cam-projections having comeinto contact with the under side of the plate Z, and raised the rack ontof connection with the pinion k', the spiral spring F immediately pullsthe sliding carrier back to its rst position, and frees The operation ofthis machine is as follows: The sliding carrier A being drawn outward bythe spiral spring F, and the rack I being also in its extremeoutwardposition and in gear with the pinion 7c', and just freed from contactwith one of the projections of the cam, the eye 2 of the carrier A willbe directly opposite to the longer end of the bobbin D, upon which thelloss, supposed to be on the running bobbins W W, is to be wound. Theend of the running loss is then attached to the larger end of bobbin D,and rotary motion given to the driving-wheel T, and consequently a rapidrotary motion will be given to the bobbin D, and at the same timevertically-sliding motions will be given to the bar G, which carrieswith it the parts H I K k L M and the cams Y Y. The inclined bar H, inconsequence of the up-and-down motions of the bar G, runs in the grooveof pulley 4, and during the downward motions of bar Gforces the lever Ebefore it, and thus moves the sliding carrier A, so as to cause its eyeor loop 2 to pass from the head of spool D toward the smaller end of thelatter and carry the running loss with it, so that it will be woundspirally around the bobbin D; and during the upward motions of bar G thespiral spring will draw the sliding carrier A back to its originalposition, and at the same time cause the running floss to be woundaround in opposite spirals upon the bobbin D. Thus, about one third ofthe length of bobbin D will be covered by two layers of the floss 5 butas the wheel M, and consequently the rack I and the inclined bar H, aremoved forward or inward by the pawl N a short distance every time thebar G rises, the inclination of the bar H will be slightly increased,and, therefore, the extent of motion in the lever E will be increasedproportionately, and the eye or loop 2'will carry the running lossproportionately farther along toward the smaller end of bobbin D, and soon until the crossing spirals reach from head to tail of bobbin D, atwhich time one of the cams Y will release the rack from the teeth ofwheel K, and allow said rack to be pushed outward to its originalposition by the lever E acted upon by the spring F through the slidingcarrier A.' The cop of lloss being now inished the machine may bestopped, the bobbin D drawn off by hand, with the lloss accurately woundin uniformly regular crossing spirals, without any risk of deranging thecoils or breaking the cop, leaving the machine ready for a repetition ofthe same operation on another bobbin.

It will be understood without any further explanation, that this machinewill automatically wind the rloss upon the bobbin D in a regular andperfect manner, and with great rapidity.

I claim as my invention- The combination, with the vertically-slidingbar G, operated as described, of the inclined bar H, rack I, pinion k',cams Y Y, Wheel K, worm-wheel L, ratchet-wheel M, and pawl N, operatingas described, for the purpose of actuatin g the vibratory lever E andsliding carrier A, in laying the running floss on the bobbin D insuccessive crossing spirals gradually extended from the head to the tailof said bobbin, as set forth.
